RFC_READ_TABLE Restrictions #

Especially with older SAP releases you may encounter a few restrictions when using the SAP standard function module (RFC_READ_TABLE) for table extraction:

  • The overall length of all columns to be extracted must not exceed 512 bytes.
  • Depending on the SAP version there may be other restrictions. It is not possible to extract data from tables that contain one or more columns of the data type f (FLTP, floating point), DEC (decimal, e.g. for percentage) or x (RAW, LRAW).
  • Poor extraction performance with larger tables.

If the above-mentioned restrictions hinder your work, install the Theobald Software custom function module Z_THEO_READ_TABLE on your SAP system.

Warning! Error while converting value ‘*.0’ of row 1530, column 3
The SAP standard module RFC_READ_TABLE for table extraction can only extract the ABAP data type DEC to a limited extent. This leads to the mentioned example error during extraction.
Use the function module from Theobald Software Z_THEO_READ_TABLE.

Installing the ABAP Framework Z_THEO_READ_TABLE #

There are two transports, one for SAP systems >= 7.40 SP5 (Z_THEO_READ_TABLE.zip), and one for systems with a lower version (Z_THEO_READ_TABLE-before_740SP05.zip).

  • Z_THEO_READ_TABLE-before_740SP05.zip contains version 1.x (till 1.11) of Z_THEO_READ_TABLE - the single custom function module.
  • Z_THEO_READ_TABLE.zip contains version 2.x of Z_THEO_READ_TABLE - the custom function module, a number of ABAP classes and other DDIC objects.

Note: Take a look at the README.txt in the installation directory (e.g.,C:\Program Files\XtractProduct\ABAP\README.txt) before installing any custom function modules.

When importing the Z_THEO_READ_TABLE-before_740SP05 on older SAP releases a syntax error may occur. Contact Theobald Software support and send the dedicated error message text.
